Title: A method of and apparatus for determining the content of fissile material in fuel samples or fuel elements of nuclear reactors
IPC: G21C17/06
Filed: 1968-06-11
Abstract: 1,235,324. Measuring fuel element fissile material content. KERNFORSCHUNGSANLAGE JULICH G.m.b.H. June 11, 1968 [June 22, 1967], No. 27761/68. Heading G1A. [Also in Divisions G4-6]  The amount of usable fissile material remaining in a fuel element is determined by removing the element from the reactor, irradiating the element to produce short-lived fission products, and then comparing the drop in activity over a predetermined time with that for a similarly irradiated element of known fissile material content. In the arrangement of Fig. 3, a fuel element is removed from the reactor 18 and conveyed to a station 19 where a rough activity measurement is carried out and moderator elements are separated from it for return on line a to the reactor. The fuel element is conveyed through the reactor on line b where on passage through station 20 it is irradiated. The element then passes through the activity measurement stations A, B, where the activity drop over a short time of the fission products formed during the irradiation, is measured. In the arrangement shown, this comprises two scintillation counters, the time taken for the element to be conveyed from one to the other, constituting the predetermined time over which the activity drop occurs. Alternatively, the activity at two separate times is measured by the same scintillation counter. The activity drop is compared with that for a fuel element of known fissile material content to decide at station 21, if the element is to be returned, on line e, to the reactor, or rejected, at d. Timing and sequencing are controlled by arrangement 22. The alternative activity measurement arrangements are described in detail with reference to Figs. 1 and 2 (not shown). In the two detector arrangements, the detector outputs feed amplifers (8), pulse energy discriminators (10) and counters (11), the difference of the two outputs being recorded in data processing unit (12), being modified by the output of dead-time analysis (9). The arrangement has facility for dealing with a sequence of samples. All calculations are carried out in data processing unit (12). In the single detector arrangement, the counts are printed out (17) for subsequent evaluation manually or recorded on a reversible counter. The fuel elements may be rotated in front of the detector collimator, during measurements.

Title: Method of producing electrically conductive and transparent layers on insulating bodies
IPC: C03C17/245
Filed: 1955-09-30
Abstract: Electrically conductive, optically transparent layers of tin oxide are deposited on an insulating base by thermal decomposition of vapours of tin tetra or dichloride in the presence of air, the thickness and distribution of the layer being controlled by the distribution and intensity of the heating to which the insulating body is subjected.  As shown in Fig. 1, a glass bulb 1 is <PICT:0791667/III/1> <PICT:0791667/III/2> <PICT:0791667/III/3> <PICT:0791667/III/4> surrounded by an annular heat radiator 4 and SnCl4 vapour, preferably in a nitrogenous atmosphere is supplied through a nozzle 3 and removed by suction at 2.  Air is drawn in around the nozzle 3.  A uniform layer 5 corresponding to the area of the radiating body 4 is deposited on the bulb.  According to Fig. 2, the bulb is heated by a heat radiator 4 and a mask 6 is interposed between the heater and the object to be coated whereby the deposit 5 is formed opposite the hole in the mask.  The mask 6 may be cooled by liquids.  In Fig. 3, a spiral heating filament enclosed in a tubular insulating body is passed around a tube 1 which is supplied by SnCl4 or SnCl2 from a nozzle 3 whereby a helical coating is formed on the inside wall of the tube 1. Similarly by arranging a heat radiating body of predetermined shape adjacent the object to be coated a predetermined distribution of layer thickness may be obtained.  The body to be coated may be heated by di-electric heating as shown in Fig. 5 where the container 8 is fed with tin tetrachloride vapours through nozzle 3, and the body 1 to be coated is placed between two electrodes 7 supplied with high-frequency voltage.  Depending on the shape of the electrodes or the relative movement of the body thereto, layers of different shape and thickness may be obtained.  The arrangement may also be adapted to record variations in high-frequency energy by causing relative movement between the electrodes and the body to be coated whereby the variations are reproduced in the form of variations in the conductive layer.  The conductive layers may be formed on the walls of electric discharge tubes to avoid wall charges or to obtain electrical screening, or to coat cathode-ray or tuning-indicator tubes, for the manufacture of helices or attenuator coatings for travelling wave tubes, for the manufacture of high power electrical resistors, particularly inside discharge tubes, to provide voltage supply to electrodes in electric discharge tubes and to establish electrical connections of elements of an electric circuit arranged on an insulating plate.

Title: Improvements in and relating to the cooling and solidifying of aluminium sulphate
IPC: C01F7/746
Filed: 1955-10-05
Abstract: <PICT:0812265/III/1> <PICT:0812265/III/2> <PICT:0812265/III/3> Solid aluminium sulphate in nodular form is produced by directing the molten material in subdivided form on to a continuously moving mass of solid bodies.  In the illustrated embodiment liquid aluminium sulphate is passed through pipe 22 to a nozzle 21 producing a sheet of liquid which is broken up by an air blast introduced through pipe 18 and nozzle 20a.  Alternatively a jet 40 (Fig. 3) can be used.  The droplets fall on to a mass 25 of preformed nodules or cast and broken particles of aluminium sulphate, or inert bodies such as pebbles or flints, in a rotary horizontal drum 10.  Nodules are built up in size and discharged through opening 16.  This drum is preferably rotated at such a speed that the particles therein cascade over one another rather than merely sliding in the drum, and vanes 35 may be provided, whereby particles are raised and subsequently dropped on to an inclined screen 27: oversize nodules are discharged and smaller particles are returned for further treatment.  The liquid is preferably directed on to the falling particles in this case. When using inert bodies as the formers for the nodules, the latter may be passed from the drum to a ball mill in which the aluminium sulphate coatings are pulverized and separated from the inert bodies which are returned to the drum if desired after heating (to increase the proportion of water-soluble alumina in the product as a result of evaporation of water) or cooling (to facilitate solidification).  The liquid passed to the jet should be at or below the boiling point, about 114 DEG  C., at normal pressure but may be superheated so that some flash evaporation may take place on discharge from the spray nozzle.  Cooling of the material in the drum may be assisted by partly covering the discharge end with a cover 28 provided with a suction pipe 29. Reference is made to Specification 812,266, [Group XIII], which describes and claims the apparatus.
